The letters AR in firearm designations, such as the AR-15 rifle, stand for ArmaLite Rifle, named after the company ArmaLite that developed the original design in the 1950s. It is a common misconception that "AR" stands for "assault rifle" or "automatic rifle"; these interpretations are incorrect.
Origin and Meaning of "AR"
The designation "AR" is a direct reference to the ArmaLite company, which was responsible for designing a series of firearms, including the AR-10 and later the AR-15, in the mid-20th century. When ArmaLite designed the original AR-15, they named it after their company, following a standard naming convention for their products.
- ArmaLite: The company that engineered the initial designs.
- Rifle: Indicates the type of firearm.
This naming convention is similar to how "AK" in AK-47 stands for "Avtomat Kalashnikova" (Kalashnikov's Automatic), referring to its designer Mikhail Kalashnikov.
Addressing Common Misconceptions
It is crucial to clarify that "AR" does not signify the firearm's operational capability or its intended use. Many widely held beliefs about what "AR" means are inaccurate:
- AR does NOT stand for "Assault Rifle."
- AR does NOT stand for "Automatic Rifle."
These terms are often incorrectly associated with "AR" due to misunderstandings about firearm terminology and design. The AR-15, for instance, is a semi-automatic rifle, meaning it fires one shot per trigger pull and is not a fully automatic weapon designed for sustained automatic fire.
Understanding "AR-15-Style Rifles"
AR-15-style rifles are not "assault weapons" or "assault rifles." An assault rifle, by definition, is typically a selective-fire military rifle that can switch between semi-automatic and fully automatic or burst-fire modes. Modern Sporting Rifles (MSRs), which are civilian versions often based on the AR-15 design, are generally semi-automatic only.
To further illustrate the correct meaning versus common misunderstandings, consider the following table:
| Term | What "AR" Stands For | What "AR" Does NOT Stand For |
|---|---|---|
| AR-15 | ArmaLite Rifle | Assault Rifle |
| Automatic Rifle | ||
| Origin | Company Name | Weapon Capability |
| Developed in | 1950s | - |

The Legacy and Impact
ArmaLite's innovative designs, particularly the AR-10 and AR-15, had a significant impact on military and civilian firearms. While the AR-15 design was eventually sold to Colt's Manufacturing Company, and further developed into the M16 for military use, the "AR" designation remains a historical nod to its original developer. Today, countless manufacturers produce AR-15-style rifles, all carrying the "AR" prefix as a tribute to the foundational ArmaLite design.
This historical context helps to understand that the "AR" prefix is simply a model designation reflecting its lineage, not an indicator of its modern capabilities or legal classification.
